ruby - Using .split on a string in an array -


इनपुट के लिए 12,34,56; 78,91; 50,60;

I अर्द्ध-बृहदान्त्र सीमा से स्ट्रिंग को विभाजित करना चाहते हैं और फिर उन स्ट्रिंग को अल्पविराम से विभाजित करना

ex: 

  डालता है "इनपुट:" input = gets.chomp s_array = input .split (",") के लिए I में 0 ..s_array.size puts s_array [i] .split (",")

यह सफलतापूर्वक साथ डालता है < / कोड> लेकिन मुझे एक त्रुटि मिलती है 

  अपरिभाषित विधि शून्य के लिए 'विभाजन': NilClass & lt; NoMethodError & gt;

इस त्रुटि का कारण क्या है?

बदलें .. के लिए ... 

  i में 0 ... s_array.size

के लिए .. के साथ एक श्रेणी शामिल है, जबकि ... नहीं है, उदाहरण के लिए 

  1..5 # = & gt; 1,2,3,4,5 1 ... 5 # = & gt; 1,2,3,4

तो चर i आपके मामले में यदि आपके आकार में सरणी आकार 5 है, array_s [5] तो शून्य होगा ।

ios - How do I use CFArrayRef in Swift? -

Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
